Gemini Jack's U Rent AllBe First in the Universe!When they accidentally walk backwards, Tod and his twin sister Tessa notice a flashing neon sign in the mall. There's something strange about it—instead of blinking on and off, the sign appears and disappears. One minute it's there, then no neon, no sign, nothing. And that's only the first clue that this is no ordinary store. Gemini Jack rents all sorts of things that the twins have never even imagined. Maybe Tod and Tessa can rent something to help them deal with the only other set of twins in their grade, Nancy and Ned. They're so mean that double trouble only describes one of them. And they get away with everything. But why is Jack so interested in meeting the evil twins?
